Hello dear !

Yes to Pursue engineering in Canada after completion of diploma in india you must need to appear SAT entrance exam for admission along with which you must qualify in english proficiency tests for admission which is the eligibility criteria .

But B.tech in Canada is a 4 year course . So your admission is based on 12th percentage,  diploma marks and english proficiency test

Few colleges might have entrance exam like SAT as common one

Few might take admission through 12th , diploma and English proficiency test marks.

Hope its helpful

Any queries drop down in the comment box

Good luck!
